Russia is currently in the process of expanding and modernizing its navy. This might have something to do with Moscow's apparent appetite for military conquest - although Russia also has a few nuclear submarines that are dangerously past their prime, considering the fissile materials that are still stored onboard.
In 2009, one rusted behemoth was transported to a factory in the far eastern port city of Vladivostok, close to the Korean peninsula, for decommissioning.
With the vessel fully out of water, the pictures offer an amazing perspective on how massive and complex even an outdated class of nuclear submarine really is.

Spent fuel and nuclear waste make decommissioning nuclear subs a high-stakes and time-consuming project. Not to mention expensive: it's going to cost an estimated $2.2 billion for Russia to full decommission its obsolete nuclear vessels.
